NBSE Grading System

Nagaland Board Grades are preferred to marks as it is felt that marks awarded to a student in any subject are subjected to different kinds of errors in evaluation.

The coverage of content in the question paper, the type of questions set, their difficulty value, inter-examiner variability in the standard of marking are some of the factors that affect the reliability of marks.

Hence, it is felt that a student who scores 65 marks out of 100, maybe anywhere in a wide range of 60 to 70 (depending on the error of measurement).

The Nagaland Board has adopted the following scheme for Relative Grading:

Grade

% of examinees

Terms of performance

A+

Top 1%

Truly Outstanding

A1

Next 5%

A2

Next 12%

Excellent

B1

An example (Please NOTE, it is an example and the distribution of marks in the ranges will change according to the performance of the examinees in that particular subject) of showing the cut off marks for distribution of raw marks on relative grading is shown below:
